   |   | Notes: The locations of SW2 & SW3 are unidentified. To |
   |   | install an internal modem as either COM1 or COM2, the  |
   |   | PAL chip at U65 must be replaced with a SER1 U58EC     |
   |   | chip. Hyundai no longer stocks this chip and there is  |
   |   | no third party sources known. The location of U65 is   |
   |   | unidentified.                                          |
